Other than exchanging gifts, sending out Christmas greetings is one of my favorite rituals during the holidays. Although you can find a whole lot of hilarious and witty cards online, but I was in the mood to find some season's greetings for the geek in you and in me.

And then I found some fun geeky stuff, from Star Wars to QR codes, from #FFFF to retro Super Mario greetings, binary stuff and of course the evergreen Pac-Man. The minimalist image on the left is one of my favorites.

Check out my collection of 15 cards that will make you and your loved ones smile geekily this Christmas:
